The method also includes loading the first set of customized data processing modules into a data plane container, wherein the network application is executed via a network operating system, and wherein, upon execution of the network application the customized data processing module causes the data plane container of the network application to process packets differently than prior to loading the customized data processing module in the data plane container.

BACKGROUND

Since the inception of computer networks, the size of networks has grown exponentially. Today, any number of computing devices may be connected over a network, and data and services provided by those devices may be accessed from any number of locations. With that growth, the complexity of managing and troubleshooting networks has dramatically increased.

At the same time a new set of applications in the area of data centers and cloud computing are pushing the requirements of dynamic provisioning and dynamic instantiation of the network infrastructure. These requirements are rapidly expanding in other segments of the IT infrastructures where networking applies.

In traditional computer networks, data paths are implemented by interconnecting switches, routers, and other network devices throughout the network. Traditional computer networks can be too rigid and complex for these new environment requirements. Network virtualization is a set of evolving concepts aiming at allowing network administrators to have control over traffic across the network without physically modifying network devices. Network virtualization is one of the use cases usually associated to software defined networking solutions.

The method also includes loading the first set of customized data processing modules into a data plane container, wherein the network application is executed via a network operating system, and wherein, upon execution of the network application the customized data processing module causes the data plane container of the network application to process packets differently than prior to loading the customized data processing module in the data plane container.

In general, in one aspect, the invention relates to a method of network application development. The method includes receiving, by a control plane object model compiler, an uncompiled object model of the control plane of a first network application, and compiling the uncompiled object model to generate a compiled object model of the control plane of the network application and a programmatic interface for the network application. The method also includes loading the user interface into an interface gateway, wherein, upon execution of the first network application the interface gateway communicates with the compiled object model of the control plane using the programmatic interface, and wherein the control plane of the network application communicates with a first set of customized data processing modules of a data plane of the first network application.

In general, in one aspect, the invention relates to a computer program product including computer readable code executable by a processor to receive, by a data plane definition language compiler, a first data plane definition describing customized functionality of a data plane of a first network application, and compile the data plane definition to generate a first set of customized data processing modules and a program interface that allows a control plane of the network application to access the first set of customized data processing modules. The computer readable code is also executable by a computer processor to load the first set of customized data processing modules into a data plane container, wherein the network application is executed via a network operating system, and wherein, upon execution of the network application the customized data processing module causes the data plane container of the network application to process packets differently than prior to loading the customized data processing module in the data plane container.

Turning to the figures, FIG. 1 depicts a network application architecture, as exists in the prior art. Specifically, FIG. 1 depicts a current data flow for a network application architecture. As depicted, FIG. 1 includes a provisioning interface 105 and a network application 110. A user, such as a network application administrator, can transmit commands to the network application 110 via provisioning interface 105. The provisioning interface 105 may include, for example, a graphical user interface (GUI), a command line interface, or an application programming interface (API).

Network application 110 includes control plane 115 and data plane 120. Control plane 115 includes a southbound API 125. Control plane 115 receives commands, such as provisioning commands, from a user, and based on control plane logic internal to control plane 115, control plane 115 directs data plane 120 on how to perform certain networking functions on network data packets 135 in the data plane 120.

The communication between control plane 115 and data plane 120 is conducted through a set of APIs. Southbound API 125 allows data to pass between the control plane 115 and the data plane 120 in order to provide instructions to the data plane 120. Specifically, southbound API 125 allows data to be transmitted from control plane 115.

FIG. 2 depicts a networking architecture well understood in the networking world. Specifically, FIG. 2 depicts a network operating system (NOS), or controller, 210 communicably connected to a network application control plane 205 and a data plane 215. In one or more embodiments, network application control plane 205 may include one or more network applications. The system depicted in FIG. 2 shows how current systems deliver more than one network application within a system. The control plane 205 of the network application, rather than communicating directly with the data plane 215, interacts with the controller or NOS 210 that, in turn, communicates with the data plane 215. Communication across the NOS 210 is achieved by northbound API 220 and southbound API 225. Data is received by NOS 210 from network application control plane 205 via northbound API 220. In addition, data is transmitted from NOS 210 to data plane 215 via southbound API 225. At data plane 215, data is received at data plane API 230.

FIG. 3 depicts a networking architecture, in which the invention may be practiced, according to one or more embodiments. Specifically, FIG. 3 depicts a network environment in which one or more network administrators may manage network applications, according to one or more embodiments. As depicted, the network includes a network application control plane 315, a network operating system (NOS, or controller) 320, and a data plane 325. Each of control plane 315, data plane 325, and NOS 320 may be stored across one or more computing devices including one or more of a computer processor, memory, and a computer readable storage device including computer code executable by the computer processor. Memory may be random access memory (RAM), cache memory, flash memory, or any other kind of storage structure or device that is configured to store computer instructions/code executable by a computer processor to store data utilized during such execution. The computer readable storage device may be any kind of computer storage device, volatile or non-volatile, such as a hard disk, an optical drive such as a compact disk drive or digital video disk (DVD) drive, and a flash memory drive.

In one or more embodiments, the control plane 315 of the network application includes an orchestration API 330, a network operating system API 335, and a southbound API 340. Each of orchestration API 330, NOS API 335, and southbound API 340 is a programmatic interface that includes computer code executable by a computer processor to allow users or external modules to interoperate with the control plane 315. Specifically, orchestration API 330 allows a user or other management module to communicate with control plane 315. NOS API 335 is a programmatic interface that includes computer code that allows the control plane 315 to communicably connect to a network operating system 335. Southbound API 340 is a programmatic interface that allows the control plane to communicate with the data plane 325 in order to control the behavior of data plane 325.

In one or more embodiments. NOS 320 includes an application services API 345 and a data plane services API 350. Application services API is a programmatic interface that interacts with NOS API 335 to allow NOS 325 to communicate with control plane 315. In addition, in one or more embodiments, NOS Application services API 345 receives instruction from an infrastructure administrator 310, or other management module in the system. NOS data plane services API 350 is a programmatic interface that allows NOS 320 to communicate with data plane 325.

As depicted, data plane 325 includes NOS API 355 and DP API 360. In one or more embodiments, NOS API 355 is a programmatic interface that allows NOS 320 to communicate with data plane 325 via NOS data plane services API 350. DP API 360 is a programmatic interface that allows data pane 325 to receive management instructions from control plane 315 via southbound API 340.

Each of the control plane 315, data plane 325, and NOS 320 may be managed by one or more human, mechanical, or computational administrators. As depicted, network application admin 305 manages the control plane 315, while infrastructure admin 310 manages the NOS 320. However, those skilled in the art will appreciate that any of network application admin 305 and infrastructure admin 310 may be replaced by a single entity, or one or more computing modules.

According to one or more embodiments, the system depicted in FIG. 3 allows for the instantiation of multiple concurrent Network Applications, although for purposes of clarity, FIG. 3 depicts only a single instantiation of a Network Application. The communicable linkage between the southbound API 340 of the control plane 315, and the data plane API 360, allows communication from the control plane 315 to bypass to NOS 320 and communicate directly with the data plane 325.

FIG. 4 shows a flow diagram in a detailed network architecture in which the invention may be practiced, according to one or more embodiments. Specifically, FIG. 4 includes the control plane 315 NOS 320, and data plane 325 components from FIG. 3, but illustrates with more specificity the development process of the network architecture. According to one or more embodiment, the infrastructure depicted in FIG. 4 illustrates how a software development kit (SDK) 400 may be utilized in order to customize a software-defined network environment for a particular network application. According to one or more embodiments, the customizable network environment eliminates the dependency between a network operating system, control plane, and data plane. The customizable network environment allows for better scalability, and prevents architecture gridlock so that individual components (such as control plane or data plane) may be modified independently, as needed. In addition, the customized network architecture enables a third party developer to modify preexisting functional components of a network operating system.

As depicted in FIG. 4, an SDK 400 may be utilized to generate a set of new network applications not previously envisioned when the data plane container 325 or NOS 320 were created. SDK 400 includes computer readable code executable by a computer processor to provide a development tool that allows the development of a particular network application, including generating customized network environment. SDK 400 may be a set of tools, compilers workflows and programmatic interface, such as an application program interface (API), or a more complete development environment to allow for generation of network applications. The flow of data is enumerated within FIG. 4. However, the order each data flow is marked does not necessarily indicate the order in which data flows throughout the system.

At 425, SDK is utilized in generating data plane (DP) definition 405 and control plane (CP) definition 410 for a particular network application. Although FIG. 4 depicts DP definition 405 and CP definition 410 being handled by a single instance of SDK 400, DP definition 405 and CP definition 410 may be generated on separate instances of SDK 400, and even by separate parties on separate computing devices across a distributed computing environment or network. According to one or more embodiments, DP definition 405 and CP definition 410 are received in a domain specific language.

According to one or more embodiments, DP definition 405 describes a customized functionality of a data plane of a network application. In one or embodiments, SDK 400 processes the DP definition 405 to generate DP API 360 and customized data processing module 420 for the network application. At 445, SDK 400 deploys DP API 360 into data plane 325, and at 450, SDK 400 deploys the customized data plane module 420 into the data plane 325.

In one or more embodiments, customized data processing module 420 causes the data plane 325 to process packets differently than it would prior to loading customized data processing module 420. In one or more embodiments, customized data processing modules are configured to perform functions configurable by a user. Those functions may include, for example, parse, lookup, update, and modify. According to one or more embodiments, the function of parse determines a structure of an incoming block of data into the data plane. According to one or more embodiments, the function of lookup identifies a set of relevant rules for a specific packet from a set of tables. According to one or more embodiments, the function of update includes modifying an internal state of the data processing module based on the combination of rules extracted from the lookup state and the incoming packet. According to one or more embodiments, the function of modify includes a set of rewrite capabilities to generate new headers of blocks of data that will be sent out of the data processing module.

According to one or more embodiments, CP definition 410 is uncompiled computer code for an object model of the control plane for the particular network application. In one or more embodiments, SDK 400 processes the CP definition 410 to generate a compiled control plane object model 415 and southbound API 340, as well as an orchestration API 330. At 430, SDK 400 deploys the orchestration API 330 into control plane 315. At 435, SDK 400 deploys the compiled CP object model 415 into control plane 315. At 440, SDK 400 deploys the southbound API 340 into control plane 315.

In one or more embodiments, the various components of the control plane 315 and data plane 325 of a particular network application need to be linked. The link may be generated by SDK 400 as part of processing either DP definition 405 or CP definition 410. Alternatively, the link between the various components may be generated separately from the CP and DP components, and may be generated by a third party that did not generate either the CP or DP components. As depicted, the linked code is deployed at 455 and allows the southbound API 340 and DP API 360 to become communicably connected.

In one or more embodiments, the linkage between the control plane 315 and the data plane 325 prevents the control plane 315 of a particular network application to interact with the data plane of another network application. Thus, the control plane of a first network application and the control plane of a second network application may concurrently communicate with a single data plane container to access their respective customized data processing modules. In one or more embodiments, the separation between each network application's control plane and corresponding data plane is enforced by the instructions that NOS 320 applies to data plane 325.

At block 615, and the CPOM compiler compiles the uncompiled object model to generate a program interface that allows a user or module to communicate with the control plane of the network application.

The method continues at block 620, and the CPOM compiler loads the object model into an application server 620. In one or more embodiments, the CPOM compiler may load the object model into the same or similar location as the location of a corresponding API of the network application, as described with respect to FIG. 5. The method continues at block 625, and the CPOM compiler loads the program interface into an interface gateway with the help of the NOS. The method ends at block 630.

FIG. 7 shows a flow chart depicting a method for deploying a network application, according to one or more embodiment. The method begins at block 700. At block 705. SDK 400 receives hearers corresponding to the configuration of the data plane definition. In one or more embodiments, SDK 400 includes functionality to determine a particular configuration and retrieve the corresponding header files from a data store. At 710, SDK 400 receives (or generates) the compiled version of the control plane object model 415.

At block 715, SDK 400 generates control plane code to trigger a call of defined API's in the data plane header files in response to a change of state in the object model.

At block 720, SDK 400 loads libraries into the NOS framework 320 to initialize the network application. At block 725, SDK 400 compiles the generated control plane code, and at block 530, SDK 200 deploys the network application. The method ends at block 735.

In each of the flow charts described above, one or more of the methods may be embodied in a computer readable medium containing computer readable code such that a series of steps are performed when the computer readable code is executed on a computing device. In some implementations, certain steps of the methods are combined, performed simultaneously or in a different order, or perhaps omitted, without deviating from the spirit and scope of the invention. Thus, while the method steps are described and illustrated in a particular sequence, use of a specific sequence of steps is not meant to imply any limitations on the invention. Changes may be made with regards to the sequence of steps without departing from the spirit or scope of the present invention. Use of a particular sequence is therefore, not to be taken in a limiting sense, and the scope of the present invention is defined only by the appended claims.

In one or more embodiment, the customized data processing module 850 causes the data plane container of the network application to process packets differently than prior to loading the customized data processing module in the data plane container 830. The data processing module 850 may be composed by a single instance or multiple instances. Multiple instances of the data processing module 850 may be presented as a single instance through a data plane abstraction or as multiple instances at the request of the Network Application developer.
